Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fixing assembly is used to mount the switching element on the substrate, then the switching element can be fixed, but the fixation is not stable and heat dissipation is insufficient
Solution Approach 1:
The patent merges the fixing function and heat dissipation function into a single integrated heat dissipation member. The fixing member with clips and the heat dissipation member with fins are combined to simultaneously achieve stable fixation and efficient heat dissipation, resolving the contradiction between fixation stability and heat dissipation efficiency.
Solution Approach 2:
The heat dissipation member extends in the vertical dimension with protruded fins, increasing the heat dissipation surface area in the thickness direction of the substrate. This dimensional extension allows efficient heat dissipation without compromising the fixation stability in the horizontal plane.
2Reliability
If a complex fixing structure is designed to improve fixation stability and heat dissipation, then performance improves, but assembly becomes difficult
Solution Approach 1:
The fixing assembly is segmented into modular components: a fixing member with clips for attachment, and a heat dissipation member with fins for thermal management. This segmentation allows each component to be optimized independently while simplifying the overall assembly process through standardized interfaces.
Solution Approach 2:
The clips on the fixing member are designed to elastically engage with the substrate and the heat dissipation member, allowing the assembly to self-fix without requiring additional fastening operations. The elastic deformation of the clips provides automatic positioning and secure attachment.
